Question

Using mental Maths, solve the following equation :
$12,550+11,488=?$

• A. $23,038$
• B. $23,938$
• C. $24,038$
• D. $24,138$

Answer 1

The correct option is C $24,038$

$450$ is added to $12,550$ to reach the nearest thousand ,that is $13,000.$

Similarly, $488$ is subtracted from $11,488$ to reach to nearest thousand, that is $11,000.$

$\Rightarrow 12,550+11,488$ can be split up as
$=13,000-450+11,000+488$
$=13,000+11,000+488-450$
$=24,000+38$
$=24,038$
